Collection consists of one bound receipt book (1815-1823) and seven unattached receipts of a Maryland firm, Evans & Iglehart. The receipt book contains entries received by leading nineteenth century merchants in Baltimore and Annapolis, including the signature of Johns Hopkins, Baltimore merchant and founder of The Johns Hopkins University.

Johns Hopkins (1795-1873) was a highly successful Baltimore merchant and philanthropist. He left much of his wealth to found a university and hospital in Baltimore. This collection contains manuscripts, photographs and printed material by or about Johns Hopkins and his ancestors, 1743-2005.

John Calvin French was professor of English and librarian at The Johns Hopkins University and author of "A History of the University founded by Johns Hopkins." The collection consists largely of his research and manuscript notes dealing with the founding and later development of the University dating from 1928-1957.
